To all whom t may concern:

Beit known that l, JAMES A. WHITLING, a citizen of the United States,and a resident of Healdton, in the county7 of Carter and State ofOklahoma, have invented certain new and useful improvements in Pumps, ofwhich the following is a specifi: cation.

My invention is an improvement 1n pumps, and has for its object toprovide a pump especially adapted for use in deep wells, wherein meansis provided in connection with the pump for settling the sand before itcomes into contact with the valves and piston of the pump, and 4wherein.other means is providedin connection with said piston for preventing theentrance of sand to the plunger or piston and between the packingthereot1 and the barrel.

lin the drawings:

Figures 1 and 2 constitute together a longitudinal section of theimproved pump,

F igs; 3 and 4 are sections on the lines 3-3 and 4r-a respectively, ofFig. 1,

Figs. 5 and 6 are sections on the lines 5-5 and 6-6 respectively of Fig.2.

lin the present embodiment of the invention, the improved pump consistsoi a tubular casing composed oi an upper section 1 and a lower section2, the said sections being connected by a union in the form of atransverse partition 3, onto whose reduced ends the sections arethreaded. The union is provided at its center with an opening 4:, andthe upper end of the opening is roamed and threaded-to receive the lowerend of the barrel 5 to be later described.

To the lower end of the section 2a reducing union is connected, theupper end of the union being reduced and threaded to engage the lowerend of the section 2. A perforate pipe or anchor 7 is engaged wlth thelower or small end of the reducing means.

A -pipe section 8 is threaded into the 'upper reduced end of the bore ofthe union 6, and this pipe carries at its upper end a check valve, whichis the foot valve of the pump. A cage 9 is connected with the upper endof the pipe by means of a reducing union 10, and within the upper end ofthis union and within the cage .there is arranged a seat 11 in the formof a ring, havlng an outwardly extending central rib whichy rests uponthe upper end of the union, the seat resting in a counterbore at theupper end of the union. A ball valve 12 cooperates Y with the seat, andthe cage has longitudi- .the perforate' section extends into a reducingunion 15 which connects the section 1 with the discharge plpe or casing16 which conducts the liquid to the top ci the weil.

Within the barrel l`13 there is arranged a plunger or piston 16 (Fig. 2)the said piston having the usual packing rings 17 held in place betweenan enlargement on the upper end of the plunger and a collar 18 threadedonto the lower end of the plunger or piston, -and the rings are spacedapart by collars 19 and 20.

Referring to Fig. 2 vit will be seen that two series of rings areprovided, the rupper series having the rings bent up, while the lowerseries are bent down, and the collar 20 is arranged between series. Aunion 21 connects the upper end of the plunger with a hollow piston rod22, and a check valve 23 is arranged within the union, vthe valvecoperating with a seat 24 similar to seat 11 and similarly mounted. Atits upper end the hollow piston rod 22 is threaded into a union 25-251,and with this union there is connected arcage 26 similar to the cage 9before mentioned. A check valve 2T is arranged within the cage, andcooperates with a seat 28 similar to the seat 11 and similarly arranged.

The union 25-25a`is sectional, consisting of an upper section 25 whichenga es the cage 26 and a lower section 25a w ich is connected with asleeve 29- 2922 This sleeve is a gland, consisting of an upper section29 and a lower section 29a which is threaded into the upper section.Packing rings 30 are arranged between the sections, and other packingrings 31 are arranged between the section 25a of the union and aninternal shoulder on the section 29 of the sleeve. The sections 25--25aof the union have cooperating clutch teeth as clearly shown in Theoperation of the improved pump is as follows: lVhen the plunger is movedup liquid is drawn up through the perforated pipe 7 and the standpipe 8,passing out through the cage 9 past the valve l2. The section 2 of theWell casing constitutes a sand chamber, as ldoes also the section l, andthe sand may settle in the chambers l and 2 about the barrel 5, andaboutthe standpipe 8, between said valve and standpipe and the chamber wall.When the plunger moves downward, the liquid in the Ylower end ofthecasing that is within the chamber 2 and within the barrel is forcedupwardly through the plunger past the valve 23 and to the hollow pistonrod past the valve 27, flowing out into the chamber in the casingsection l.

l claim:

l. A pump of the character specified comprising a casing consisting ofupper and lower sections, a stand pipe at the lower end of the lowersection through which the liquid enters into the said section, saidstand pipe extending well above the lower end of the section and havinga check controlled port at its top, a barrel extending upwardly from thelower end of the section, the space between the barrel and the saidlower end of the lower section being closed, a connection between theupper end of the barrel and the casing, said plunger being hollow andhaving a hollow piston rod connected therewith and extending to near thetop of the upper section of the casing, a section of perforate casinginterposed between the upper end of the barrel and the top of the said.upper section, a check valve at the top of the hollow iston, and apacking land at the top of t erbarrel through whic the piston.

rod moves. v

2. A pump of the character specified comprising a casing having a seriesof compartments arranged one above the other and having a stand pipeextending upward from the bottom of each compartment to form acommunication between said" compartment and the next lower compartment,the uppermost stand pipe being a pump barrel, and 'a plunger mounted toreciprocate in the barrel',

said stand pipes communicating with the compartments, in which they arearranged at their tops, the plunger being ported to melma permit thefree upward flow of liquid and to prevent its downward How.

3. A pump of the character described, comprising in combination an outercasing, a closure for each end thereof, said closures each having acentral passage. therethrough, a division wall intermediate the ends ofsaid casing having a cent-ral passage, a working barrel communicatingwith said central passage, a plunger within said working barrel having ahollow stem adapted to force Water upwardly therethrough, valve meanswhereby said water will be held against returning downwardly throughsaid plunger, an eduction pipe communicating with the upper end of saidworking barrel, a pipe disposedin the outer casing below the divisionwall and having its one end communicatin with the passage in the lowerend of lsaid casing, said pipe being of less diameter than the outercasing and extending upwardly from the lower end thereof to a pointbelow the division wall of said casing, and a check valve adapted tocontrol the flow of liquid through the upper end of said pipe.

4. pump of the character described, comprising in combination an outercasing, a closure for each end thereof,` said closures each having acentral passage therethrough, a divisionwall intermediate the ends ofsaid casing having a central passage, a working barrel communicatingwith said central passage, a plun er within said working barrel having ahol ow stem adapted to force water upwardly therethrough, valve meanswhereby said water will be held against returning downwardly throughsaid plunger, an educvtion pipe communicating with the upper end of saidworking barrel, apipe disposed in the outer casing below the divisionwall and having its one end communicating with the passage in the lowerend of said casing, said pipe being of less diameter than the outercasing and extending upwardly from the lower Vend thereof to a pointbelow the Vdivision wall of said casing, a check valve adapted tocontrol the flow of liquid through the upper end of said pipe, and acage associated with said check valve adapted to cause liquid drawnupwardly through Said pipe to spread thereabout for settling the foreignparticles therein.`
